Reclaim the automatic minutes, not every useful screen.
A total alone cannot distinguish a video call from an accidental scroll. Look at the apps and moments that feel automatic, choose a realistic daily amount, and protect only those openings. Thirty minutes a day is 182.5 hours across a year—but even five deliberate minutes still compounds.
Questions
Screen time calculator FAQ
How does the screen time calculator work?
It multiplies your daily average by seven and by 365 to show weekly hours and the equivalent number of full 24-hour days per year. The five-year view repeats the same arithmetic without assuming a lifespan.
Does GrateGuard save my screen time?
No. The calculator runs in your browser. It does not submit, save, or attach your inputs to the store links. Copying a result creates a short text summary without storing your values on GrateGuard servers.
Where can I find my daily screen time?
On iPhone, open Settings, Screen Time, then See All App & Website Activity. On many Android phones, open Settings, Digital Wellbeing & parental controls, then inspect the usage chart. Device menus can vary.
Is all screen time bad?
No. Work, learning, creating, navigation, and connecting with people can all be intentional. This tool only makes the arithmetic visible so you can decide which portion—if any—you would rather reclaim.
What changes if I reclaim 30 minutes a day?
Thirty minutes per day adds up to 182.5 hours, or about 7.6 full days, over one 365-day year. The calculator lets you choose a different target and updates the result immediately.
